I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them

Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)

Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Hugh Speirs · Apr 2026 Trustpilot

Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.

I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.

This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.

Andy Thomas · Apr 2026 Trustpilot

I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

⚠️

Known issue: SolarEdge HD-Wave inverters from certain 2017–2020 production batches have experienced higher-than-expected failure rates. If your unit is within the 12-year warranty period, SolarEdge will replace it. Keep your serial number and fault code evidence ready — these are required for the warranty claim.

Diagnostics

6-step HD-Wave failure diagnosis

Work through these steps in order. The fault code and production history from SolarEdge Go and the monitoring portal are essential for the warranty claim.

1

Check the LED panel — are all LEDs off?

Look at the front of the HD-Wave inverter. There are three LEDs: DC (left), Communication (middle), and AC/Grid (right). If all three are completely dark, the inverter has no internal power.

All LEDs off

Check the AC isolator at the consumer unit first. If the isolator is on and LEDs are still dark, the inverter's internal power supply has failed. This is the most common HD-Wave failure mode.

LEDs on but no production

The inverter is powered but not converting DC to AC. This could be an internal component failure, a DC string fault, or a firmware issue. Continue to Step 3 to read fault codes.

2

Check for thermal shutdown — is the casing excessively hot?

HD-Wave inverters are rated to approximately 60°C ambient temperature. In enclosed spaces — cupboards under stairs, unventilated lofts, south-facing walls in direct sun — the inverter can exceed its thermal limit and shut down as a protective measure.

If the casing is too hot to hold your hand on comfortably, allow it to cool for 30–60 minutes with ventilation, then check if it restarts. Repeated thermal shutdowns mean the installation location needs better airflow or the internal fan has failed.

The HD-Wave has no external fan — it uses a fanless convection design. If the internal thermal management has failed, the unit will need replacement.

3

Connect SolarEdge Go via Bluetooth and read fault codes

Open SolarEdge Go on your phone, stand within 3–4 metres of the inverter, and attempt to connect via Bluetooth. If it connects, navigate to Status and Alerts.

Hardware Error = Internal component failure — warranty replacement
AC Relay Fault = Output relay has failed — cannot export to grid
Internal Comm Failure = Internal board communication lost
Over Temperature = Thermal shutdown — check ventilation

If SolarEdge Go cannot connect at all (no Bluetooth response), the inverter's communication module has also failed — confirming a total internal failure. Screenshot the error for the warranty claim.

4

Review monitoring portal production history for failure pattern

Log in to monitoring.solaredge.com and look at the production graph over the last 1–3 months. HD-Wave inverters approaching failure typically show a characteristic pattern:

Gradual decline: Daily production peaks drop week-on-week even in similar weather conditions
Mid-day gaps: Production drops to zero during peak sunshine, then recovers — the inverter is thermally cycling
Intermittent outages: Random days with zero production followed by normal days — internal component is failing intermittently
Sudden stop: Production drops to zero and does not recover — the inverter has failed completely

Export or screenshot this production data — SolarEdge's warranty team will request it as evidence of the failure.

5

Test AC output voltage at the inverter terminal (if competent)

If you have a multimeter and are competent to use it safely, measure the AC output voltage at the inverter's external AC connection point. During daylight with DC power available, a working inverter should show approximately 230V AC output. If the LEDs are green but AC output is zero, the inverter's output stage or AC relay has failed internally.

Do not open the inverter enclosure. Do not touch DC wiring or connectors. This test is at the external AC terminal only. If you are not confident with electrical testing, skip this step and proceed to Step 6.

6

Contact an engineer for warranty assessment and replacement

If the HD-Wave has failed, contact a qualified solar engineer with the following information ready:

Inverter serial number (label on the side/bottom of the unit)
Fault codes from SolarEdge Go (screenshot if possible)
Production history showing the failure pattern
Date the system was originally installed (from MCS certificate)

The engineer will submit the warranty claim to SolarEdge with this evidence. SolarEdge typically approves within 3–5 working days and ships a replacement unit directly. The physical swap takes 2–3 hours on site. Total time from claim to working system is usually 2–4 weeks.

Why HD-Wave inverters fail — and what SolarEdge has done about it

The SolarEdge HD-Wave is a single-phase string inverter used in the majority of UK residential SolarEdge installations. The "HD-Wave" name refers to the inverter's patented power conversion topology — a distributed switching architecture that reduces the size and weight of the unit compared to conventional inverter designs. Models range from SE3000H (3kW) to SE6000H (6kW), with the SE3680H being the most common in UK systems.

Between 2017 and 2020, certain production batches of HD-Wave inverters experienced higher-than-expected failure rates. The predominant failure mode is an internal power supply or output stage fault that causes the inverter to stop producing entirely. SolarEdge has not publicly disclosed the specific component responsible, but field engineers consistently report capacitor and relay failures in affected units. The failure is typically sudden — the inverter stops producing overnight or mid-day with no preceding fault code — though some units show a gradual decline in output over several weeks before complete failure.

SolarEdge covers these failures under the standard 12-year warranty. The warranty replacement process requires the engineer to submit the serial number, fault code evidence, and production data. SolarEdge ships a replacement unit (new or refurbished) directly. The original optimisers on the panels do not need replacing — they are compatible with the replacement inverter and will re-pair automatically once the new unit is commissioned.

FAQ

SolarEdge HD-Wave failure questions

The most common causes are thermal stress from poor installation ventilation, internal component degradation in early-production units (particularly the SE3000H–SE6000H manufactured between 2017–2020), and power surge damage from grid events. SolarEdge has acknowledged higher-than-expected failure rates in certain production batches. The 12-year warranty covers these failures.
HD-Wave inverters have a standard 12-year manufacturer warranty covering component failure and manufacturing defects. SolarEdge ships a new or refurbished inverter to the engineer. Labour costs for the swap are typically not covered. Some installations have extended warranties (up to 25 years) purchased at installation. Check your original paperwork or contact SolarEdge with your serial number to confirm.
SolarEdge typically approves the warranty claim within 3–5 working days. The replacement unit ships in 5–10 working days depending on stock. The physical swap takes 2–3 hours on site. Total time from claim to working system is typically 2–4 weeks.
Yes, but with important considerations. If you replace the HD-Wave with a non-SolarEdge inverter, the power optimisers on each panel become redundant — they only work with SolarEdge inverters. Removing them and rewiring for a string inverter is a significant additional cost. The warranty replacement will be a like-for-like or equivalent current-model HD-Wave within the SolarEdge ecosystem.
Your system produces zero electricity while the inverter is failed or removed. If you are on the Smart Export Guarantee, you lose both self-consumption savings and export income. If on the legacy Feed-in Tariff, deemed export payments continue but generation payments stop. Keep a record of the dates offline for any insurance or loss-of-income claim.
